MACH-[NE FOR INSERTING PINS IN MUSlC-BAR RELS.

QPECIFICATION forming part of Letters Patent No. 315,052, dated April 7,1885.

Application filed May 1, 1884.

To aZZ whom it may concern.-

Be it known that I, HENRY B. MORRIS, a citizen of the United States,residing at Ithaca, in the county of Tompkins and State of New York,haveinvented certain new and useful Improvements in Machines forInserting Pins in Barrels for Mechanical Musical Instruments; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention consists of a machine for antomatically inserting pins atpredetermined points in rollers intended for use in mechanical musicalinstruments, such as hand-organs, forinstance. Theleading characteristicof the machine is a stepwisemovable'pattern which governs the insertionof the pins.

In order that my invention may be clearly understood, I have illustratedin the annexed drawings and will proceed to describeapractical form of amachine adapted to insert pins in a wooden roller along a spiral line.

Figure 1 is a plan View of the machine. Fig. 2 is a verticallongitudinal section in the plane indicated by broken line X X ofFig. 1. Figs. 3 to 7 illustrate details of themachine, some being drawnon alarger scale than Figs. 1 and 2 and others on the same scale.

The same letters of reference indicate identical parts in all thefigures.

The various parts of the machine are mounted on a suitable bed-plate ortable, A, provided with shears a a across one end for the support andguidance of a carriage consisting of the upright cheek-plates B B andthe parallel connecting-bars B B', the latter being fitted to the shearsa a. A horizontal roller, 0, provided at one end with a spur-wheel, D,is arranged between the cheek-plates of the carriage, the entire lengthof the roller and its spur-wheel being just equal to the distancebetween the said cheek-plates. The roller 0 is supported in part upon ahollow shaft, E, and in part upon a screw, F. The hollow shaft E,journaled in the fixed bearing A on the bed-plate, and also supported ina bearing on cheek-plate B, extends through the spur-wheel D into roller0, suitably bored nearly its whole length to fit the shaft. Thespur-Wheel D is (No model.)

provided with a spline, d, which engages alon-, gitudinal groove, e, inshaft E, so that while they are turned by the shaft Ethe spur-wheel Dand roller C may also move longitudinally thereon. At the end oppositethat entered by shaft E the roller is tapped or provided with a fixednut to screw on the screw-threaded portion of screw F, the inner smoothend of which extends into hollow shalt E forsup port. 6c

The screw-threaded portion of screw F projects through the cheek-plate Bof the carriage, and its outer end isrigidly secured to a standard, A",on the bed-plate A. The surface of the roller 0 is filled withequidistant 6 5 holes a, distributed along the convolutions of a spiralline. A live-center, G, is journaled in the upper portion of cheek-plateB. This live-center carries a fixed spur-wheel, H, of

the same diameter and having the same numher of teeth as spur-wheel D,which drives it through the medium of an intermediate spurwheel, D.Spuravheel H is provided with a drive-pin, h. Cheek-plate B carries inits 11 Jet ortion a (lead-center H screwed in pl 1 i 7a the check-plate,so that it may be adjusted. The wooden roller I, in which the pins areto be inserted, and which I term the musicroller, is centered on thecenters of the carriage, one end of the roller being provided with aneccentric hole to receive the drive pin h. g

It will be readily perceived that the turning of shaft E has the twofoldeffect of feeding the carriage together with the rollers O and 8 5 I andof rotating said'rollers synchronously i. 6., in such a manner that theycomplete a rotation in the same period of time. p

A given piece of music to be played by pins on the music-roller is setup on the surface of 0 In order to prevent the pins'c from falling outof the pattern-roller at the lower side, I provide thefeed-carriage'with a segmental trough or concave, B, concentric with andsurrounding the lower side of the pattern 0 roller at a distance aboutequal to the projec tion of the pins 0.

The devices for cutting the pins and insert ing them in the music-rollerare mounted on the table M of a stand erected on the bed-plate. The pinsare successively out by shears from a spool of wire, J, the end of whichis fed to the shears in about the horizontal plane of the axis of themusicroller by feed-rollers K K. The shears consist of a stationaryblade, L, and a pivoted blade, L, the 1ever-arm of which is pivoted on apin, M, supported on standards of table M. The side of the blades facingtoward the music-roller is fiat; but at the opposite side the blades arebeveled from the cutting-edges, as clearly shown in Fig. 2. Inconsequence of this construction the shears cut the-pin severed from thewire with asquare end, but bevel or point the end of the wi re,so thatthe point of the pins will be beveled or pointed, to facilitate drivingthem into the music-roller,while the buttend will be square.

The pivoted blade is held open by a spring,l,

which throws the arm L thereof down onto the slide N, mounted in guideson the table M. The pivoted blade is closed by the action of a cam, If,on slide Nduring the forward stroke of said slide.

In feeding the wire the end passes through between the shears into aguide-hole, 0, in the bar or transfer-block 0, which is mounted to slideon the end of table M, transversely with respect to the wire fromwhich'the pins are cut. The transfer-block is normally held by a spring,0'', in such a position that its guidehole 0 is directly in line withthe end of the wire. Each time and immediately after a pin has been outfrom the wire the'transfer-block is moved to bring the pin in line witha driver, N, on the slide N. This sliding of the'transfer-block iseffected by a lever, O pivoted on pin M, and constructed with acam-head, 0 adapted to operate on a cam -facc, 0, of transfer-block O.The tail of lever O rests on slide N (it may be held down by a spring,like lever-arm L and is operated by a cam, 0 on said slide N during theforward stroke thereofnamely, immediately after a pin has been .severedfrom the wire and before the driver N reaches the transfer-block. Cam 0has a flat extension, 0 by which the tail of lever O is kept elevated,so that its cam-head will prevent the return of the transfer-block, buthold it stationary long enough to enable the driver to drive the pinonto the music roller and withdraw from out of the guidehole of thetransfer-block. The feed-rollers K K are turned to feed the wire duringthe return-stroke of slide N by a pawl, K, there on, through theintervention of a ratchetwheel, K, on a counter-shaft, K, which carriesa spur-wheel, K for driving a spurwheel, K, on roller K. Spur-wheel Ktransmits motion to roller K by a spur-wheel, K having a like number ofteeth. The cams L and O and pawl K are suitably disposed on the slide Nto act at the proper times. The

slide N is rcciprocated, through the mediumv of an eccentric-rod, P, bythe eccentric on the main shaft Q of the machine. The eccentric P actson the eccentric-rod P through a ring, 1?, which is constructed with adog, p, and is loose on the eccentric. The eccentricrod is provided withan elongated yoke surrounding the eccentric-ring P, and so construetedthat said ring may be locked therein or unlocked therefrom, according assaid ring is turned, so as to engage a shoulder, 12, of said yoke, or soas to be disengaged from said shoulder. The eccentric will onlyreciprocate the eccentric-rod, and through it slide Nwhen the ring P islocked in the yoke of said rod.

The position of eccentric-ring P is determined by the patterurollerthrough the following means: A lever, R, is fulcrumed'onthe stand oftable M, reaching with one arm, the end of which is provided with adownwardlyprojecting pin, r, over the pattern-rollen: The other arm ofthe lever engages the lower end of a pitman, R, between a coupleof nuts,4 a, thereon. The upper end of pitman R is .pivoted to theeccentric-ring P. A stiff spring, W, is arranged between the lever B and-the nut r tending to hold the lever up against the nut r. A little inadvance of shoulderp a pin, 1", projects up through the yoke of theeccentric-rod, being normallyprojeeted by a spring, 6", which is lighterthan spring 1, but

still strong enough to ordinarily prevent the engagement of shoulder 19'by the dog 10 of the eocentricring. The lever B is so arranged andproportioned that in its oscillations, imparted to it by the eccentric,its pin r will strike down close to the surface of the pattern-roller.So long as pin r strikes no pin 0 of the pattern-roller theeccentric-ring will merely oscillate the eccentricrod but not move itendwise. But whenever the pin r of lever B strikes upon a pin, a, of thepatternroller, whereby the motion of the lever is an rested, in thatcase the pitman It turns the ring '1? on the eccentric, so as to causeits dog 19 to depress the pin 0" and engage the shoulder 1) of theeccentric-rod. The feed of the pattern-roller is so timed with referenceto the eccentric P that it takes place while the arm of the lever B,provided with the feeler-pin r, is elevated. g I

The feedcarriage, together with the patternroller and music-roller, isfed step by step by turning shaft E intermittingly. This maybe effectedby a simple ratchetand-pawl gearing; but in order to adapt the machineto operate with different sizes and styles of pattern-roll: ers and upondifferent styles and sizes of musicrollers, I prefer to use avariablegearing,substantially such as is employed on gear-cutting engines, theso-called index-plate S thereof being keyed to shaft E and operated by avariable pin on radius-bar, S, which is oscillated by the eccentric T onshaft Q through the medium of eccentricrod T, rocking arm T, andadjustable connecting-rod T The return motion of the index-plate isprevented by a pin on adjustable arm S. This mechanism IIO admits ofgreat variations in the feed of the I carriage and the rollers supportedthereon.

In summarizing the operation of the machine let it be assumed that theend of the wire has been fed into the guide-hole of the transfer'block,and that there is no pin 0 of the pattern-roller under the feeler-pin oflever B. The machine will run without operating slide N until thepattern-roller has been fed to a point where one of its pins 0 standsunder the feeler pin of lever It. On the downstroke of the feeler-pin,the dog of the eccentric-ring is caused to engage the yoke of theeccentric-rod so as to move the rod and slide Ntoward the music-roller.During this forward strokeof the slide its cam L first closesshear-blade L, cutting a pin from the wire, next its cam 0 slides thetransfer-block so as to carry the pin to a point in line with thepin-driver N, and finally the pin-driver drives the pin into themusic-roller. On the return-stroke of the slide N, after the pindriverhas withdrawn from the transfer-block, the latter is returned to itsposition of rest, shear-blade L is opened, and the pointed end of thewire fed into the transfer-block. The pattern-roller is also fed forwarda step during the return-stroke of the slide N, and the dog of theeccentricrin'g is disengaged from the shoulder 19 of the yoke of theeccentric-rod by the action of spring r and pin r". Each feed-step bothturns and advances the patternroller to such an extent as to carry itsholes 0 successively under the feeler-pin r, and the diameter of themusic-roller bears such relation to that of the pattern-roller thatwhenever there are pins 0 in successive holes of the pattern-rollersuccessive pins will be'driven into the music-roller in such closecontiguity as to constitute in effect a continuous ridge adapted tosound a prolonged note. This feature of the roller constitutes thesubject-matter of an application for United States Letters Patent filedof even date with the application for this patent.

In order to give additional support to the music'roller under the blowsof the pin-driver, I provide a back-rest, U, constructed with a rib ofproper height to bear against the back of the music-roller.

It is obvious that the pin cutting and driving mechanism may bemultiplied, each separate mechanism being governed by a separatefeeler-lever, so that the music-roller may be prepared along differentsections at one and thesame time. Again,music-rollers areusuallydesigned to play a number of pieces. Musicrollers of this descriptionmay be prepared by the machine described by first inserting all the pinsfor one piece, then after properly adjusting the music-roller endwiseinserting all the pins for the next piece, and so on; or the machine maybe adapted by a suitable multiplication of the pin cutting and drivingmechanism to prepare the roller for all the pieces at the same time. Allthese modifications I regard as mere variations of my invention, andmany other variations may be made without departing from the principleof my invention.

I believe that I am the first to provide a machine for automaticallyinserting pins in music-rollers in accordance with a previously preparedand stepwise-moved pattern, and therefore claim such machine, broadly.

As regards the pattern, its form may be much varied. Thus,instead ofusing avariable pattern, a separate unchangeable pattern may be providedfor each kind of music-roller, either in the shape of a roller or in theform of a perforated belt of the nature of J acquards cards, suitablechanges being made in the feeler-lever and connections.

Instead of cutting the pins from a spool of wire by the machine, theymay be cut by a separate machine and taken, one at a time, by the pindriver from the bottom of a suitable hopper.

To adapt the machine for preparing rollers having circular rows of pins,the screw-feed may be so modified as to advance the carriage a distanceequal to that between two adjacent rows at the completion of each fullturn of the pattern-roller.

I claim as my invention 1. A machine for inserting pins in musicrollers,organized with a stepwise-movable pattern which governs the insertion ofthe pins, substantially as set forth.

2. A machine for inserting pins in musicrollers, organized with astepwise-movable pattern which governs the insertion of the pins andwith a variable feed motion, substantially as before set forth.

3. The combination, substantially as before set forth, of thestepwise-movable pattern-roller, the feed-carriage provided with centersfor the support of the music-roller, and a driver for turning themusic-roller synchronously with the pattern-roller.

4. The combination, substantially as before set forth, of thestepwise-movable pattern, the feeler-lever,.the pin-driver, and meanscontrolled by the feeler-lever for reciprocating the pin-driver.

5. The combination, substantially as before set forth, of thereciprocating slide carrying the pin-driver and provided with cams L andO and pawl K, the wire-feed rollers, the shears, the pin-transfer block,and lever 0 6. The combination, substantially as before set forth, ofthe feed-carriage for supporting the music-roller and the back-rest.

In testimony whereof I affix my signature in presence of two witnesses.
